[0027] A support tube 703 is fixedly provided at one end of the wheel frame rod 7, and a telescopic channel 701 is opened inside the wheel frame rod 7. One end of the telescopic channel 701 is connected to the inside of the support tube 703, and an electric telescopic rod 702 is fixedly provided in the telescopic channel 701.

[0028] The inflatable cylinder structure includes a piston sleeve 107 fixedly arranged in the embedded groove 106, a mounting seat plate 116 is movably arranged in the piston sleeve 107, one side of the mounting seat plate 116 is fixedly connected to the end of the piston rod 114, the other side of the mounting seat plate 116 is provided with a piston 119, and the side of the mounting seat plate 116 facing the outer wheel body 110 is provided with a first one-way air valve 123. The side of the embedded groove 106 facing the inflatable chamber 122 is connected to the inflatable chamber 122 through a spring embedded hole 117, a connecting channel 124 and a contraction chamber 121 which are sequentially provided, a return spring 118 is arranged in the spring embedded hole 117, one end of the return spring 118 is fixedly connected to the piston 119, and the other end of the return spring 118 is fixedly connected to the inner end surface of the spring embedded hole 117, the inner contour of the contraction chamber 121 is in the shape of a truncated cone, and an air cushion 120 is arranged in the contraction chamber 121.

[0029] A rim 111 is provided along the edge of the outer side of the outer wheel body 110, and a tire 112 is provided on the outer side of the rim 111. Protective covers 104 are provided on both sides between the center wheel shaft 102 and the outer wheel body 110. In actual applications, a plurality of ventilation holes are provided on the protective cover 104, and an annular insert 109 is fixedly provided on the outer edge of the protective cover 104. An annular mounting groove 108 for inserting the annular insert 109 is provided on the outer wheel body 110. The annular insert 109 is fixedly connected to the outer wheel body 110 by bolts. A through-axis hole is provided at the center of the protective cover 104, and the inner side of the through-axis hole is rotatably connected to the center wheel shaft 102 through a first bearing 105.

[0030] In actual applications, when pressurizing and inflating the inflation chamber 122, when the guide wheel 115 moves from the corner of the guide wheel groove 113 to the middle of the edge line, the guide wheel 115 drives the mounting plate 116 and the piston 119 to slide and move in the piston cylinder sleeve 107 through the piston rod 114. In actual applications, the mounting plate 116 and the piston 119 are fixedly connected to each other only at the center point, so that when the mounting plate 116 moves upward, the piston 119 cannot be supported by the mounting plate 116 over a large area, and thus deforms, causing gas to enter the piston cylinder sleeve 107 under the mounting plate 116, and when the mounting plate 116 moves downward, the piston 119 is supported by the mounting plate 116 over a large area, and at this time, the outer edge of the piston 119 and the inner wall of the piston cylinder sleeve 107 are sealed against each other. Similarly, the commonly used structure of the piston in the air pump in the prior art can also be adopted, that is, when the piston 119 is always in sealing contact with the inner wall of the piston cylinder sleeve 107, a one-way air valve is arranged on the piston 119, and the above-mentioned inflation function can also be achieved. At this time, the return spring 118 is in a compressed state, so that the piston 119 inflates the air in the piston cylinder sleeve 107 toward the inside of the inflation chamber 122. At this time, the air cushion 120 is deformed toward the inflation chamber 122 by the impact of the air flow, so that the piston cylinder sleeve 107 and the inflation chamber 122 are connected. At this time, the first one-way air valve 123 is negatively charged in the piston cylinder sleeve 107. Under the action of pressure, air is taken in from the outside to the inside, and when the guide wheel 115 moves from the middle to the corner of the edge line of the guide wheel groove 113, the piston 119 and the piston rod 114 are pushed toward the outer wheel body 110 under the elastic force of the return spring 118. At this time, the air cushion 120 closes the port of the connecting channel 124. When the piston 119 is in the piston cylinder sleeve 107 toward the outer wheel body 110, the outer edge of the piston 119 is deformed under the push of the air pressure in the piston cylinder sleeve 107, thereby moving the gas in the piston cylinder sleeve 107 toward the spring embedding hole 117, thereby performing a reciprocating cycle of inflation.

[0031] Working principle and effect of the present invention: The vehicle body 2 moves under the support of the front wheel 1 and the inner wheel body 101, wherein the front wheel 1 has two use states. The first use state is that the front wheel 1 can rotate relative to the wheel frame rod 7, and the front wheel 1 is used as a normal wheel. The second use state is that the front wheel 1 can be fixed relative to the wheel frame rod 7. At this time, the front wheel 1 can inflate the air tank 6 through the air duct 3; the electric telescopic rod 702 push rod in the wheel frame rod 7 extends, thereby driving the slider 704 to telescopically move in the telescopic channel 701. When the electric telescopic rod 702 push rod reaches the maximum stroke, the latching tooth 705 is inserted into the tooth groove 706 provided on the outer side of the center wheel shaft 102, thereby realizing the position of the center wheel shaft 102 relative to the wheel frame rod 7; the electric telescopic rod 702 push rod in the wheel frame rod 7 retracts, Thereby, the slider 704 is driven to telescopically move in the telescopic channel 701. When the push rod of the electric telescopic rod 702 reaches the minimum stroke, the latching tooth 705 and the tooth groove 706 are separated from each other, thereby enabling the center wheel shaft 102 to rotate relative to the wheel frame rod 7; when the front wheel 1 is in the second usage state, when the front wheel 1 moves forward, the position between the center wheel shaft 102 and the wheel frame rod 7 is relatively fixed, and the outer wheel body 110 rotates relatively on the outside of the inner wheel body 101, thereby enabling the guide wheel 115 to roll along the guide wheel groove 113. During this process, the piston rod 114 drives the mounting seat plate 116 and the piston 119 to telescopically move in the piston cylinder sleeve 107, thereby enabling the inflation into the inflation chamber 122, and the gas in the inflation chamber 122 is added to the gas storage tank 6 through the gas guide pipe 3. More specifically, when the front wheel 1 is used in the first usage state, it is used for driving on flat roads and uphill driving, etc., and when the front wheel 1 is used in the second usage state, it is used for driving downhill and braking driving, etc. In addition, the front wheel 1 can also be suspended in the air, and the air tank 6 can be inflated by rotating the front wheel 1.

[0032] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

Protective covers (104) are arranged on both sides between the central wheel shaft (102) and the outer wheel body (110), and an annular insert ring (109) is fixedly arranged on the outer edge of the protective cover (104). An annular mounting groove (108) for inserting the annular insert ring (109) is provided on the outer wheel body (110), and the annular insert ring (109) is fixedly connected to the outer wheel body (110) by bolts. A through-axis hole is provided at the center of the protective cover (104), and the inner side of the through-axis hole is rotatably connected to the central wheel shaft (102) by a first bearing (105).

10. A method for using an air-powered vehicle with kinetic energy recovery, using the air-powered vehicle with kinetic energy recovery as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1: The vehicle body (2) moves under the support of the front wheel (1) and the inner wheel body (101), wherein the front wheel (1) has two use states, a first use state in which the front wheel (1) can rotate relative to the wheel frame rod (7), and the front wheel (1) is used as a normal wheel, and a second use state in which the front wheel (1) can be fixed relative to the wheel frame rod (7), and at this time, the front wheel (1) can inflate the air storage tank (6) through the air guide pipe (3); S2: In step S1, the push rod of the electric telescopic rod (702) in the wheel frame rod (7) is extended, thereby driving the slider (704) to telescopically move in the telescopic channel (701). When the push rod of the electric telescopic rod (702) reaches the maximum stroke, the latching teeth (705) are latched into the tooth grooves (706) provided on the outer side of the central wheel shaft (102), thereby achieving the position of the central wheel shaft (102) relative to the wheel frame rod (7); S3: In step S1, the push rod of the electric telescopic rod (702) in the wheel frame rod (7) is retracted, thereby driving the slider (704) to telescopically move in the telescopic channel (701), and when the push rod of the electric telescopic rod (702) reaches the minimum stroke, the latching teeth (705) and the tooth grooves (706) are separated from each other, thereby enabling the central wheel shaft (102) to rotate relative to the wheel frame rod (7); S4: When the front wheel (1) is in the second use state, the front wheel (1) moves forward, so that the position between the central wheel shaft (102) and the wheel frame rod (7) is relatively fixed, and the outer wheel body (110) rotates relatively on the outer side of the inner wheel body (101), thereby achieving the rolling movement of the guide wheel (115) along the guide wheel groove (113). During this process, the piston rod (114) drives the mounting seat plate (116) and the piston (119) to move telescopically in the piston cylinder sleeve (107), thereby achieving the inflation of the inflation chamber (122), and the gas in the inflation chamber (122) is added to the gas storage tank (6) through the gas guide pipe (3).
